Egypt has been under months-long state of emergency, which has already been extended once, following deadly church bombings and attacks on Coptic Christians that have killed more than 100 people and wounded scores since December.
Egypt's President Abdel Fattah al-Sisi extended for the second time a state of emergency first declared following deadly church bombings in April, in a decree issued in the official gazette Thursday.
The attacks were claimed by the Islamic State.
"The state of emergency will be applied across the country, effective as of 1 a.m. Friday, for an additional three months due to ongoing security concerns", read a presidential decree.
President Sisi renewed it for a third term starting tomorrow, local media reported.
"The armed forces and the police will take the necessary measures to confront the dangers of terrorism", it said.
The state of emergency allows authorities to make arrests without warrants and search people's homes.
Hundreds of police and army personnel have been killed since then.
